"It is natural for a soil to be covered with vegetation, and when the land is continually under the plow and only one crop is grown, an unnatural condition exists, and as a result there is a loss of fertility.” 

Quote by Harry Snyder, University of Minnesota Soil Scientist, 1900

The purpose of the South Dakota No-Till Association is to promote, advance and improve agriculture through the utilization of no-till farming methods.  To encourage, aid and conduct research of no-till farming practices and disseminate educational information to producers using or wanting to use no-till cropping systems.
